EuP Ready Motherboard

EuP Ready Power Supply

EuP System

What is EuP?
EuP, stands for Energy Using Product, was a provision regulated by European Union to define the power consumption for the completed system. With the great quantity and the popularly using of the electrical products nowadays and the continuously increasing of the electrical products categories in the following 20 to 30 years, European Union decided to establish an effective strategy to solve the energy consumption problem. That is, according to EuP, the total AC power of the completed system shall be under 1.00W in off mode condition.
How to setup an EuP system?
To meet EuP standard, the EuP ready motherboard and the EuP ready power supply are required. As a motherboard vendor with eco-awareness, ASRock is the pioneer to develop EuP Ready motherboards based on the great efforts of our exceptional hardware design. According to Intel, the EuP ready power supply must meet the standard of 5v standby power efficiency is higher than 50% under 100 mA current consumption. For EuP ready power supply selection, please check with the power supply manufacturer for more details.
ASRock, Worldwide First EuP Ready Motherboard Manufacturer!
ASRock hereby proudly announced that we are the Worldwide First motherboard manufacturer to release EuP Ready motherboard to the market! With ASRock EuP Ready motherboard, you are confident to setup a system to pass the EuP standard.

A785GMH 128M

Step 3
Press Save button to save the CPU_OC3.8GHz OC settings as a profile.

Step 4

Send the CPU_OC3.8GHz profile to other friends.

Step 5

When the friend receives your CPU_OC3.8GHz profile, he can press Load to load the CPU_OC3.8GHz profile in OC DNA.

Step 6

After that, the friend can enter into BIOS OC Tweaker menu to load the CPU_OC3.8GHz profile as his BIOS OC settings.
Now, you have successfully share your OC setting profile with your friends.
*The OC DNA works only when users use the same motherboard and BIOS version.

ASRock Instant Flash

ASRock Instant Flash is an exclusive and the most userfriendly BIOS flash utility developed by ASRock. It is embedded in Flash ROM which is used to update the system BIOS without having to enter operating systems like MS-DOS or Windows.

Features

Once executing ASRock Instant Flash, the utility will automatically detect all devices such as USB, hard disk or even floppy drive to find the exact BIOS for your system. Instead of giving you all BIOS in your devices, the Instant Flash just list BIOS versions that apply to your motherboard model only. For example, if you have many different BIOS of different motherboards saved in your devices, but you just need to flash your P45 motherboard, the Instant Flash will just list the P45 BIOS versions for you. This unique function allows you to easily select the suitable BIOS version instead of browsing through all data.

Instant Flash just list BIOS versions that apply to your motherboard model.
Click and start Flashing!
